The 40G QSFP+ transceiver module connects the electrical circuitry of the system with either a copper or an optical external network. The transceiver is used primarily in short reach applications in switches, routers, and data center equipment where it provides higher density than SFP+ modules.This article will focus on attaching the optical network cable and removing the 40G QSFP+ Transceiver Module.

Attaching the Optical Network Cable

Before removing the dust plugs and making any optical connections, follow these guidelines:

1:Keep the protective dust plugs installed in the unplugged fiber-optic cable connectors and in the transceiver optical bores until you are ready to make a connection.

2:Inspect and clean the MPO connector or the duplex LC connector end faces just before you make any connections. See the Tip following step 2 in the next procedure for a pointer to a fiber-optic inspection and cleaning white paper.

3:Grasp the MPO or the duplex LC connector only by the connector housing to plug or unplug a fiber-optic cable.

Step 5: Verify that the optical network cable is fully seated by pulling gently on the cable’s MPO or duplex LC connector boot. If the network cable disconnects, reinstall it and make sure that the cable connector is fully seated and that the connector latch engages.
